Responding to the call to test Rawhide on lesser machines, I made a 32 bit boot.iso disk and attempted a network install. Things proceeded smoothly until Anaconda choked on one of the Packages - network manager config or some such. I rsynced just now and tried to install 32 bit Rawhide on another machine using pxeboot. Same results but it choked on a different package.
A new pxeboot network install of 64 rawhide installed on that second machine without problems. This appears to be a 32 bit problem.
